SCHEDULING PROVISIONS: ---------------------- 8.1 Nevada Power shall endeavor to preschedule energy in the manner described hereunder. Nevada Power may modify existing preschedules or submit Real-Time schedules subject to provisions under Section 8.4, 8.5 and 8.6 hereunder. 8.2 Los Angeles shall establish one energy Account and one corresponding energy loss Account for Nevada Power's use for scheduling under this Agreement. 8.3 Schedules shall be submitted to Los Angeles' Schedulers for inclusion in the Los Angeles interchange preschedule by 1100 hours (Pacific Time) on the day prior to the effective date of the Schedule. Schedules for weekend, NERC holiday and national holidays shall be submitted in accordance with prevailing WSCC procedures, or as determined by Los Angeles' Schedulers, whichever calls for the earlier submittal. 4 Nevada Power shall submit NERC transaction tags corresponding to each Schedule as required by WSCC. 8.4 If Nevada Power desires to modify its Schedule after the Preschedule period or to submit Real-Time Schedules, Nevada Power shall notify Los Angeles' Dispatcher at least one hour in advance of the hour when such Schedules are to become effective, provided that an Account for such transmission path has been previously established. 8.5 At those times when Nevada Power requests that the Schedule be modified or submits a Real-Time Schedule due to an emergency on Nevada Power's electric system, Los Angeles will make best efforts to accommodate Nevada Power's request as soon as possible. 8.6 In the event Nevada Power's Scheduling Ability is curtailed in real time pursuant to Section 7 herein, Nevada Power shall, immediately after oral notification by Los Angeles' Dispatcher, reduce Nevada Power's Schedule in the amount determined by Los Angeles. 8.7 Whenever Nevada Power becomes aware of any condition, external to Los Angeles' Control Area, which requires that Nevada Power reduce its Schedules hereunder, Nevada Power shall orally notify Los Angeles' Dispatcher of such condition and Los Angeles' Dispatcher shall reduce Nevada Power's Schedules in the amount determined by Nevada Power. 8.8 Los Angeles shall not be obligated to perform any scheduling and or accounting for any Third Party. 8.9 Los Angeles reserves the right to curtail Schedules under this Agreement whenever Los Angeles determines, in its sole judgement, that such Schedules do not correspond precisely to other simultaneous Schedules at the Point of Receipt and the Point of Delivery, that such Schedules are part of an incomplete or insufficient transaction path, or that such Schedules violate WSCC scheduling policies. 8.10 As an inclusion in the transmission service rates pursuant to Section 10 hereunder, Nevada Power is entitled to submit one NERC transaction tag per day free of charge during the entire period of this Agreement. Los Angeles reserves the right to charge up to $87.36 per revision whenever Nevada Power desires to make a request to modify its existing Schedule during the day. For the purposes of this section, a single Schedule or revision, which prevailing WSCC procedures may require to be presented on multiple NERC tags, shall be counted as one tag. 8.11 The Authorized Representatives shall coordinate changes to the scheduling and dispatching procedures in this Section 8 to conform to Los Angeles' overall system operation as such may be changed from time to time. 9. TRANSMISSION LOSSES: -------------------- 5 9.1 Transmission losses associated with the energy scheduled pursuant to this Agreement shall be the responsibility of Nevada Power. The amount of such losses shall be deemed to be 6.36 percent of the energy transmitted between NOB and MCC500. 9.2 Transmission loss shall be settled financially unless it is mutually agreed to settle pursuant to Section 9.3 hereunder. Nevada Power shall pay Los Angeles, for each month, an amount equal to the hourly California Power Exchange Market Clearing Price in the "day of" market at Eldorado/MCC500 multiplied by the losses incurred hereunder during each hour of the month. 9.3 Nevada Power shall have the right to request that the transmission loss incurred hereunder during the month be returned to Los Angeles with the actual energy provided by Nevada Power in accordance with Los Angeles's schedule/accounting procedure. In that event, unless otherwise notified, Nevada Power is assumed to return the losses concurrent with the scheduled energy. Nevada Power may need to purchase additional transmission to cover such losses. 10.
